I’m sure you’ve heard the phrase, “Don’t get pushy.” Well, in the automotive world this phrase seems to have taken on a new meaning. In the last 10 to 15 years or so the number of buttons on a motor vehicle seems to have grown immensely. I remember back in the early days of my automotive career there were fewer buttons to push on the dash and more levers or sliding cable-operated controls than there are on today’s vehicles.
It’s all about information. The more we know, the better job we can do. No one is an expert on everything. That’s where information sharing becomes so critical. Every tech has faced a problem wherein the remedy isn’t easily found in a repair manual. When a specific problem is faced and a technician discovers a fix, sharing that information with others helps those who may be faced with the same challenge. We’re in this together, so let’s help each other out.
Like most shops, mine has become increasingly populated with cordless power equipment, ranging from impact wrenches, drills, saws, grinders, vacuums, a wide array of flashlights, tablets, cell phones, cordless desk phones and on and on.
Turbochargers are essentially compressors that direct more air into the engine’s cylinders in order to produce additional power. A turbo derives its energy source from both temp and pressure of exhaust gas. Intake air enters through the air cleaner into the turbo compressor inlet. The air is compressed which raises air density and volume.
The need to track down electrical system failures in today’s vehicles are more prevalent now than they were many years ago. With the addition of system add-ons such as increased safety items, more entertainment and creature comfort options and overall improved vehicle operating capabilities, the technician is faced with the added complexity of performing proper diagnostics.
The Supplemental Restraint System (SRS); or in GM jargon SIR (supplemental inflatable restraint system) uses more components than just airbags: modules, crash sensors, seat weight and position sensors, seat belt switches, warning lights and pre-tensioning devices are all used to protect and enhance the safety of the driver and passengers.
Diagnosing chassis issues, including noise, vibration and drivability concerns ranges from the simple to the difficult-to-pinpoint. In this article we’ll discuss a variety of tips, both vehicle-specific and generic. As part of the article, we’ve included insightful comments from Federal-Mogul Motorparts and Arnott.
Windshield wipers are an integral component on almost anything that moves, including planes, boats, trains, cars and trucks. And if you think they really haven’t changed much since Mary Anderson invented them in 1903, you are mistaken.
When you talk about diagnostics in the automotive industry, the first thing that usually comes to mind is a computer problem like an engine system, anti-lock brake system or maybe even a body control issue.
This happens frequently, with many shops experiencing a frustrating issue with what we tend to identify as “difficult” customers. A passenger car enters the shop for a reported “brake noise.” Your inspection reveals badly scored front rotors, a badly rusted right rear rotor, stuck calipers, badly worn front pads and flexible brake hoses that have seen better days.
